CISCO Security Advisory

Published Date: May 14, 2026

Advisory Summary

🔔 Cisco has updated its security advisory concerning the previously reported denial of service (DoS) condition in Cisco Crosswork Network Controller and Cisco Network Services Orchestrator (NSO). After thorough investigation, the Cisco Product Security Incident Response Team (PSIRT) has reclassified this incident. It is now identified as a customer-configurable resource management issue rather than a security vulnerability, indicating no direct security threat but emphasizing the importance of proper configuration to avoid resource exhaustion.

â„šī¸ This reclassification shifts the advisory from a critical security alert to an informational notice, helping network administrators focus on appropriate resource allocation and system management to maintain stability and avoid service interruptions.

Administrators should review their configurations in these Cisco platforms to ensure optimal resource management and prevent potential service degradation.
